DETAILED DESCRIPTION

Embodiments of the present invention provide systems and methods fortransmitting haptic messages.

Illustrative Embodiment of Transmitting Haptic Messages

One illustrative embodiment of the present invention comprises a mobiledevice such as a mobile phone. In the illustrative embodiment, themobile device comprises the Samsung SGH-i710 mobile computer equippedwith Immersion Corporation's VibeTonz® vibrotactile feedback system. Inanother embodiment, the messaging device comprises ImmersionCorporations TouchSense® Technology system also known as ImmersionTouchSense® vibrotactile feedback system. Other mobile devices andhaptic feedback systems may be utilized.

The mobile device comprises a display, a user interface device, memory,and a processor in communication with each of these elements. Thedisplay comprises a touch-sensitive display, or a touch-screen. Theillustrative mobile device also comprises a sensor and an actuator, bothof which are in communication with the processor. The sensor isconfigured to sense a user's physical interaction with the mobiledevice, and the actuator is configured to output a haptic effect to theuser.

In the illustrative embodiment, a multi-dimensional message inbox in theform of a virtual message environment is shown on the display. Thevirtual message environment contains electronic messages represented asvirtual message objects. A message may be for example comprise text,data, pictures, video, or audio. A message may be displayed as a virtualmessage object which comprises the message. A virtual message object maytake the form of: a scroll, a capsule, a ball, a balloon, or any otherobject that the display is capable of displaying. Each type of virtualmessage object may correspond to a specific type of message. Forexample, virtual message objects in the form of a tube or a cylindricalscroll may represent text messages or chat conversations. A shortmessage intended to convey emotion, such as intimacy, may be representedas a virtual message object in the form of a heart. The virtual messageenvironment also comprises a virtual gateway. Virtual message objectsmay enter or leave the virtual message environment through the virtualgateway.

In the illustrative embodiment, the virtual message object comprises atoken. A token is a type of virtual message object that displays thesame characteristics in both the sending and receiving mobile devices.Thus, when a virtual message object is sent from one mobile device toanother, the virtual message object displays the same characteristics inthe recipient device as it displayed in the sending device. Thecharacteristics which are maintained may comprise the virtual messageobject's size, shape, color, and any haptic effect associated with thevirtual message object. In some embodiments, a token may be a businesstoken, a personal token, or some other type of token.

With the illustrative device, users can interact with the virtualmessage environment and/or virtual message objects by using thetouch-screen and/or by manipulating the mobile device, for example, byrotating or shaking the device. Through such interactions, users cancreate, manipulate, send, and/or receive virtual message objects. In theillustrative device, a user makes a gesture directed toward the virtualgateway to transmit a virtual message object. Example gestures include:engaging the touch-screen and dragging or flicking a virtual messageobject toward a virtual gateway, tilting the mobile device in thedirection of the virtual gateway, or shaking the virtual mobile device.

The sensor detects the user's gesture and, based on this gesture, sendsa sensor signal to the processor. The sensor may comprise: a gyroscope,an accelerometer, a GPS, or other sensors capable of detecting movement,orientation, or location of the mobile device. The sensor may beconfigured to detect when a user moves or tilts the device. Based atleast in part on the sensor signal, the processor determines a virtualforce to apply to the virtual message object. For example, when thedevice is tilted, the processor may determine a virtual forcerepresenting gravity, and move the virtual message object in thedirection the device is tilted. As another example, a sensor may detectthat the device has been jabbed or thrust toward a virtual gateway. Thesensor will then send a corresponding signal to the processor, which maydetermine a virtual force and apply it to the virtual message object.

After receiving a sensor signal, the processor determines a transmissioncharacteristic of a virtual message object based, at least in part, onthe sensor signal. In the illustrative embodiment, a transmissioncharacteristic comprises a characteristic or property associated withthe user's gesture or how the virtual message object was sent throughthe virtual gateway. This transmission characteristic is preserved andmay be included as a part of the message. In one example, a user sendsan urgent message by forcefully pushing the virtual message objectthrough the virtual gateway. The transmission characteristic of thevirtual message object will comprise its velocity as it passes throughthe virtual gateway. In another example, after a user slowly drags orflicks a virtual message object toward the virtual gateway, theprocessor determines a slow transmission characteristic. Additionally,the processor may determine other transmission characteristics based onthe sensor signal, such as an approach angle transmission characteristicbased on the angle of the user's gesture. The processor then includesthe virtual transmission characteristic as a part of the virtual messageobject. In some embodiments, the processor may further include adetermined haptic effect.

Next, the processor determines whether to transmit the virtual messageobject based, at least in part, on the virtual force. This determinationmay include a calculation of whether the gesture was sufficientlydirected toward the virtual gateway. If a gesture is not directed towardthe virtual gateway, the processor may determine that the virtualmessage object should not be transmitted, but rather it should stayinside the local virtual message environment. If the gesture issufficiently directed toward the virtual gateway, the processor willdetermine that the virtual message object should be transmitted.

Finally, the processor transmits the virtual message object, as well asthe transmission characteristic. The processor may send the virtualmessage object and the transmission characteristic to a networkinterface, such as a cellular network interface or a Wi-Fi networkinterface. The network interface then transmits the virtual messageobject and the transmission characteristic over a network, such as acellular network, intranet, or the Internet, to another mobile device.

In another embodiment of the illustrative device, virtual messageobjects are transmitted to the recipient device at substantially realtime. For example, a user may create a virtual message object on thesending device, and at substantially the same time the same virtualmessage object may appear on the recipient device. In this embodiment,the sender may manipulate characteristics of the virtual message objectand those modifications may appear at substantially the same time on therecipient device. For example, a user may modify the color or hapticeffect associated with a virtual message object on the sending mobiledevice, and at the same time, the virtual message object may be modifiedon the recipient device's screen. Thus, a virtual message object mayform a direct real-time connection between two mobile devices. In thisembodiment, signals associated with virtual message objects are sent,even though the user has not used a send function, or moved the virtualmessage object through the virtual gateway.

When the illustrative device receives a virtual message object, itstransmission characteristic may be preserved and interpreted by thereceiving mobile device. In the illustrative embodiment, the user'sindicative gesture comprises a fast flick toward the virtual gateway. Afast transmission characteristic is determined by the processor andtransmitted along with the virtual message object. Then, when theillustrative device receives the virtual message object, it displays thevirtual message object entering its graphical user interface through avirtual gateway. The virtual message travels through the receivingdevice's virtual gateway with a velocity and haptic effect correspondingto its transmission characteristic. In the illustrative embodiment, auser sent the message with a fast flick, thus the receiving device'sprocessor will determine a strong haptic effect, such as a heavy thud ora bounce. The processor may further determine a violent collision insidethe virtual message environment when the virtual message object enters.In an alternative embodiment, if a user sent the virtual message objectwith a gentle thrust or tilt, the virtual message object may arrive at aslower speed accompanied by a gentle haptic effect, such as a softvibration.

This illustrative example is given to introduce the reader to thegeneral subject matter discussed herein; the invention is not limited tothis example. The following sections describe various additionalembodiments and examples of methods and systems for transmitting hapticmessages.

Transmitting Haptic Messages

Embodiments of the invention presented herein provide systems andmethods for transmitting haptic messages. By incorporating a physicalmodel into a virtual message environment, embodiments can leverage auser's everyday tactile experience and motor-sensory skills tointuitively navigate the user interface in order to control thetransmission of messages. Conventional messaging systems may providelittle or no intuitive gesture navigation. Text messaging systems usinga conventional email metaphor, with a one-dimensional inbox showingsubject lines, drafts, etc., may be visually and cognitively intensive,requiring a user's heightened attention for creating, sending, andreceiving messages. Further, conventional messaging systems may retainlittle or no contextual information associated with how the message wassent. Transmitting messages haptically, however, can facilitatenon-linguistic communication of content by tying physical effects to amessage.

In one embodiment, the mobile device's graphical user interface displaysa virtual message environment. This virtual message environmentincorporates a physical model, which allows users to directly manipulateits contents. The virtual message environment comprises electronicmessages which are displayed as virtual message objects. A virtualmessage object may take the form of a ball, a scroll, a capsule, anarrow, a heart, or other shapes. Users can manipulate virtual messageobjects and the virtual message environment through motions or gesturesdetected by various sensors. These sensors may comprise one or more of agyroscope, GPS, accelerometer, touch-screen, or other sensors configuredto detect motion. The user's gestures or movements are translated intovirtual forces acting on virtual message objects. These forces may causethe virtual message objects to move and collide inside the virtualmessage environment or to exit the environment through a virtualgateway.

Further, using a physical modeling engine, virtual boundaries may beprogrammed to correspond to the physical boundaries of the screen of thedevice. In such an environment, a virtual message object can bounceagainst the boundaries of the virtual message environment withouttraveling off the screen. A virtual gateway in the environment may becreated by replacing part of the virtual physical boundary with agateway or portal to one or more recipients. When a virtual object movesthrough the virtual gateway, it is transmitted to one or more recipientdevices, and “leaves” the host's virtual message environment.Additionally, the virtual gateway may be closed, disabling the abilityto send messages and keeping unsent messages in the virtual messageenvironment. Thus, embodiments of the present invention may utilize aspatial metaphor for sending messages, thereby facilitating a moreintuitive messaging process.

In some embodiments, a user may move a virtual message object throughthe virtual gateway by making an indicative gesture toward the virtualgateway. The gesture may be made by contacting the virtual messageobject on the touch-screen, moving the entire mobile device, or throughsome other means. In one example, a user sends a virtual message objectby selecting it on the touch-screen and using a flicking gesture to movethe object toward the virtual gateway. The processor may determine atransmission characteristic, such as the speed of the virtual messageobject as it travels through the virtual gateway. The transmissioncharacteristic may be preserved as the virtual message object istransmitted to another mobile device. When the virtual message object isreceived by a recipient device, it may arrive in the virtual messageenvironment and behave or interact with other objects and/or theenvironment based, at least in part, on its transmission characteristic.

In other embodiments, the virtual message environment itself maycomprise a virtual gateway to the recipient device. For example, when avirtual message object is created in a sending virtual messageenvironment, it may appear substantially simultaneously in the recipientvirtual message environment. In another embodiment, if a user modifies avirtual message object by adding text or a haptic effect to the virtualmessage object, these changes may take place substantiallysimultaneously in the receiving virtual message environment.

Illustrative Systems for Transmitting Haptic Messages

In reference to the drawings in which like numerals indicate likeelements throughout the several figures, FIG. 1 is a block diagram of asystem for transmitting haptic messages according to one embodiment ofthe present invention. As shown in FIG. 1, the system 100 comprises amobile device 102, such as a mobile phone, portable digital assistant(PDA), portable media player, or portable gaming device. The mobiledevice 102 comprises a processor 110 in communication with a networkinterface 112, a sensor 114, a display 116, an actuator 118, a speaker120, and a track ball 122.

The processor 110 is configured to generate a graphical user interfacewhich is shown on display 116. Processor 110 is in communication withnetwork interface 112, which may comprise one or more methods of mobilecommunication, such as infrared, radio, Wi-Fi, or cellular networkcommunication. In other variations, network interface 112 comprises awired network interface, such as Ethernet. The mobile device 102 can beconfigured to exchange messages or virtual message objects with otherdevices (not shown in FIG. 1) via network interface 112. Embodiments ofmessages exchanged between devices may comprise voice messages, textmessages, data messages, or other types of messages.

The processor 110 is also in communication with one or more sensors 114.Sensor 114 may comprise a position sensor, location sensor, rotationalvelocity sensor, image sensor, pressure sensor, or another type ofsensor. For example, sensor 114 may comprise an accelerometer, agyroscope, a GPS sensor, a touch-sensitive input device (e.g. touchscreen, touch-pad), or some other type of sensor. The one or moresensors 114 may be configured to detect changes in, for example,acceleration, inclination, inertia, or location. For example, the mobiledevice 102 may comprise an accelerometer 114 configured to measure theacceleration of the mobile device 102. The one or more sensors 114 areconfigured to detect a user interaction and send a signal representingthe user interaction to processor 110. The mobile device 102 maycomprise additional forms of input, such as track ball 122, buttons,keys, a scroll wheel, and/or a joystick (not shown in FIG. 1).

Users may interact with the user interface through movements orgestures, the one or more sensors 114 detect these movements. As theuser tilts, shakes, thrusts, or otherwise moves mobile device 102, theone or more sensors 114 detect these movements. The sensors 114 generatesensor signals based, at least in part, on these movements and sendthose signals to processor 110. The signals may comprise one or more of:angle of the movement, speed of the movement, distance covered by themovement, or X-Y orientation of the movement. In one embodiment, anaccelerometer sensor is configured to detect the inclination andacceleration of the mobile device 102. As the mobile device 102 istilted, an accelerometer can be configured to send signals to theprocessor 110 based, at least in part, on the tilt and/or accelerationof the mobile device 102.

Signals received from the sensor 114 may be associated with aninteraction with the graphical user interface shown on display 116. Inone embodiment, a sensor signal comprises an indicative gesture orientedtoward a virtual gateway in a virtual message environment. For example,an indicative gesture may comprise a poking motion which moves themobile device 102 in a certain direction. An accelerometer 114 maydetect the poking motion and send a sensor signal to the processor 110representing the motion. As another example, an indicative gesture maycomprise dragging or flicking a virtual message object toward a virtualgateway. A touch-screen display 116 may detect the drag or flick andsend a representative sensor signal to the processor 110.

In the embodiment shown in FIG. 1, processor 110 is also incommunication with display 116, which is configured to display agraphical user interface. Display 116 may comprise a touch-sensitiveinput device, such as a touch-screen, configured to send/receive signalsto/from processor 110. The graphical user interface shown on thetouch-screen display 116 facilitates the user's interaction with themessages. The graphical user interface comprises a virtual messageenvironment, in which messages are represented as virtual messageobjects. A virtual message object may be selected and manipulated bycontacting it directly via touch-screen display 116. In one mode ofinteraction, two-dimensional finger gestures on a touch screen displaymay select, drag, flick, throw, and/or move a virtual object within thevirtual message environment.

Signals received from a touch-screen display 116 may be associated witha transmission characteristic of a virtual message object in a graphicaluser interface. In one variation, a predetermined gesture ontouch-screen 116, such as flicking or dragging a virtual message object,may be associated with a transmission characteristic, such as speedand/or angle of transmission of the virtual message object. In oneembodiment, a quick flick is associated with a fast transmissioncharacteristic of a virtual message object, while in another embodiment,a slow drag is associated with a slow transmission characteristic.

The processor 110 may determine a haptic feedback effect based, at leastin part, on a virtual message object's transmission characteristic. Inone variation, a user indicates that a virtual message object should besent to another user by quickly jabbing the mobile device 102 in thedirection of a virtual gateway. Based on the quick jab, processor 110determines a fast transmission characteristic and that the virtualmessage object should be transmitted. Then the processor 110 determinesa haptic effect, such as a quick vibration, based at least in part onthe fast transmission characteristic. Finally, processor 110 transmits ahaptic signal representing the haptic effect to actuator 118.

As shown in FIG. 1, the processor 110 is also in communication with oneor more actuators 118. Actuator 118 is configured to receive a hapticsignal from processor 110 and output a haptic effect. After processor110 determines a haptic effect, it sends a haptic signal to actuator118. The haptic signal is configured to cause actuator 118 to output thedetermined haptic effect. Actuator 118 may be, for example, apiezoelectric actuator, an electric motor, an electro-magnetic actuator,a voice coil, a linear resonant actuator, a shape memory alloy, anelectro-active polymer, a solenoid, an eccentric rotating mass motor(ERM) or a linear resonant actuator (LRA).

Processor 110 is also in communication with a track ball 122. Processor110 may receive signals representing user interaction from track ball122. For example, track ball 122 may be used to scroll or navigatethrough a menu of message recipients in an address book. After arecipient has been selected, the track ball may be pressed to confirmthe selection of a recipient. When the track ball 122 is pressed, avirtual gateway associated with the selected recipient may be displayedin the virtual message environment. When a virtual gateway is displayed,the processor 110 is ready to send the virtual message object to aparticular recipient.

FIG. 2 is an illustration of a system for transmitting haptic messagesaccording to one embodiment of the present invention. The elements ofsystem 200 are described with reference to the block diagram depicted inFIG. 1. A variety of implementations other than that shown in FIG. 1 arepossible.

As shown in FIG. 2, system 200 comprises a mobile device 102, such as amobile phone, PDA, portable media player, or portable gaming device. Themobile device 102 is configured to send and receive signals, such asvoice mail, text messages, and other data messages, over a network suchas a cellular network or the Internet. The mobile device 102 maycomprise a wireless network interface and/or a wired network interface112. Although the device 102 is illustrated as a handheld mobile devicein FIG. 2, other embodiments may comprise different devices, such asvideo game systems and/or personal computers.

As shown in FIG. 2, the mobile device 102 comprises a display 116. Inaddition to display 116, the mobile device 102 may comprise buttons, atouchpad, a scroll wheel, a rocker switch, a joystick, or other forms ofinput devices (not shown in FIG. 2). Additionally, display 116 maycomprise a touch-sensitive input device, such as a touch screen.

Display 116 is in communication with processor 110. Display 116 isconfigured to display virtual message environment 210, and may compriseone or more virtual message objects. Virtual message objects may takethe shape of any object display 116 is capable of showing. For example,virtual message objects may take the form of: arrows, balls, capsules,hearts, and tubes. As shown in FIG. 2, the virtual message environment210 comprises three virtual message objects 220 a, 220 b, and 220 c.Inside the virtual message environment 210, virtual message objects 220a, 220 b, and 220 c may move freely, bouncing and colliding with othervirtual message objects and the boundaries of the virtual messageenvironment 210.

Each virtual message object may represent a message and/or a file, suchas a text message, a picture, a video, a voicemail, a reminder, or apseudo-emotional message such as a smiley face or a frowning face. Thecontent of a virtual message object may be used determine the shape ofthe virtual message object. For example, a virtual message object in theform of a tube or a rolled-up scroll 220 c may represent a text message.Or a virtual message object in the form of an egg or a capsule 220 a mayrepresent a message with an attachment, such as a video file, a picture,or a song. Virtual message objects may also represent various forms ofnon-verbal communication, such as gestures, facial expressions, oremotions. For example, virtual message object 220 b, shown as a ball,may correspond to a non-verbal message such as an indication ofplayfulness. A virtual message object represented as an arrow mayrepresent a poke or a jabbing gesture (i.e. to request or demandattention). Other virtual message objects may appear as a heart, abasketball, a water balloon, a typewriter, or another shape that display116 is capable of displaying. Effective virtual message objects compriseeasily identifiable visual and/or haptic properties and/or effects. Forexample, a virtual message object can represent a work file in the formof a typewriter and include a haptic effect that represents the clangingkeys of a typewriter. Or the virtual message object representing anunimportant email may be in the form of a bowling ball and include ahaptic effect which represents a bowling ball hitting pins.

A virtual message object may comprise a data store definingcharacteristics of the virtual message object. These characteristics mayinclude information regarding how the virtual message object interactswith other virtual message objects and the boundaries of the virtualmessage environment. For example, in one embodiment, a virtual messageobject may appear in the form of a rubber ball and include data whichcauses the ball to easily bounce off other virtual message objects. Inanother embodiment a virtual message object may appear in the form of anegg, and contain data which causes the egg to easily shatter if impactedby another virtual message object.

Representing messages as virtual message objects enables a user toquickly determine information about a message without opening it. Insome embodiments, the size of a message corresponds to the size or massof the virtual message object. A message with a large file attachmentcan be represented as a large or massive object. The haptic collisioneffect associated with a large or massive object may be composed ofstrong (high magnitude) vibrations. A message such as a short textmessage or a message with a small file attachment can be represented asa small virtual message object. The haptic collision effect associatedwith a small virtual message object may be composed of soft (lowmagnitude) vibrations. In this way, all of the physical properties(visual appearance, haptic characteristics, etc.) are interrelated. Thisenables the user to gather information about the virtual message objectand its contents from multiple sources at once.

In some embodiments, a virtual message object may comprise a textmessage. In such an embodiment, the virtual message object may includepre-written text. In other embodiments, the user may enter unique textfor a virtual message object. In such an embodiment, the user interactswith the virtual message object to indicating that the user wishes toenter text. For example, such an interaction may comprise double-tappingthe virtual message object. Sensor 114 or track ball 122 detects theuser interaction, and transmits a corresponding signal to processor 110.Based on the received signal, processor 110, generates a text box, anddisplays this text box on display 116. In some embodiments, the text boxmay comprise a simple QWERTY keyboard for entering text. In otherembodiments, the textbox may be more complex. For example, the text boxmay comprise a virtual representation of an old-fashioned mechanicaltypewriter. In such an embodiment, when the user depresses a key of themechanical typewriter, the processor 110 may output an audio signal andhaptic effect corresponding to the typewriter's clanging keys. Inanother embodiment, the textbox may comprise a blank sheet of paper,that the user can write on by interacting with the mobile device. Forexample, using a touch-screen, the user could sign their name usingtheir finger or a stylus. In another example the user may write acomplete message using their finger or a stylus. In other embodiments,the user may move the entire mobile device in pattern substantiallyapproximating text. In such an embodiment, the display may show avirtual object in the form of a spray-paint can. When the user wishes toenter text, the user may press the spray-paint can and move the mobiledevice in a pattern substantially approximating the text the user wishesto enter. Sensor 114 may detect the movement, and transmit acorresponding signal to processor 110. Based on the received signal,processor 110 determines the entered text.

In some embodiments, a user may embed a haptic effect into a specificwords within the text message. In such an embodiment, the user may entera text message, and then interact with a specific word within the textmessage. Sensor 114 or Track ball 122 may detect the interaction andtransmit a corresponding signal to processor 110. In such an embodiment,the user interaction may comprise double-clicking a specific word withina text message. Based on the received signal, processor 110 maydetermine that the user intends to add a haptic effect to a word. Theprocessor 110 may then transmit an audio, haptic or visual signals whichindicate that the processor 110 is ready to receive haptic information.The user may then enter a haptic effect, which the processor 110 appendsto the word. In some embodiments, the haptic effect is pre-loaded on themobile device. In other embodiments, the user may enter a new hapticeffect via sensor 114. In such an embodiment, the user may shake themobile device, and sensor 114 may detect the movement and transmit acorresponding signal to processor 110. Based on the received signal,processor 110 may determine a new haptic effect which corresponds to theshaking of the mobile device. Then, when the user transmits the messageto a recipient, the recipient may touch the word, and feel theassociated haptic effect. For example, in one embodiment a user may senda message including the word “love.” In such an embodiment, the user mayappend a haptic effect comprising a beating heart to the word love. Thenthe recipient can feel the beating heart when the recipient interactswith the word love. In another embodiment, a user may enter theirsignature, and append a haptic effect to their signature. Such anembodiment may allow the user to attach a haptic signature to messages.

The virtual message environment 210 also comprises a virtual gateway212. A virtual message object may be sent to other mobile devices bymoving it through the virtual gateway 212. As a virtual message objectmoves through the virtual gateway 212, it is transmitted to a recipientdevice and “leaves” the local virtual message environment 210. Thus,embodiments of the invention may utilize a spatial metaphor for sendingmessages, facilitating a more intuitive process of sending messages.

The virtual gateway 212 may be displayed by replacing a section of thevirtual message environment 210 with the virtual gateway 212. Thevirtual gateway 212 may comprise a visual indication of the recipient(s)it is directed toward. For example, the virtual gateway 212 may show thename of a selected recipient. In FIG. 2, “Noah” is shown as thepotential recipient of a virtual message object sent through the virtualgateway 212. In another variation, a group of recipients, such as a“family” group or a “classmates” group may be shown in the virtualgateway 212. In such a variation, when a virtual message object is sentthrough a virtual gateway 212 indicating a recipient group, the virtualmessage object is sent to the mobile device of each individual in thegroup.

In method 300, processor 110 receives a recipient signal associated witha recipient of the virtual message object 306. Processor 110 may receivea recipient signal from a button, scroll wheel, or other input device,such as track ball 122 or sensor 114. In one embodiment, processor 110displays a sequential list of names from an address book stored in localmemory. The names can be shown in the virtual message environment 210,for example, at the top or the bottom of the display 116. To scrollthrough the names, a left or right button is pressed. When the correctname for the intended recipient has been identified, the track ball 122may be depressed to send a recipient signal to the processor 110. In onevariation, a user may scroll through names in an address list by shakingthe device in a left or right direction. With a small, soft shake, theprocessor 110 may progress through the address list by small increments,such as one or two names in either direction. With a large, violentshake, processor 110 may progress through the address list by largerincrements, such as ten or twenty names in either direction.

Next, processor 110 displays virtual gateway 212 in the virtual messageenvironment 308. Virtual Gateway 212 may be associated with therecipient of a virtual message object. For example, virtual gateway 212may comprise a visual indication of a recipient by displaying the nameof the recipient. In the event of a network failure, processor 110 mayclose the virtual gateway 212, yielding visual and/or haptic cues to theuser that a virtual message object cannot be sent. In one variation,when processor 110 determines that a recipient cannot receive a virtualmessage object, the virtual message object may bounce against thevirtual gateway 212 and remain in the virtual message environment 210.Once the virtual gateway 212 has been established, a virtual messageobject may be sent to a recipient. The virtual message object may besent with a gesture moving it toward the virtual gateway 212.

Next, processor 110 receives a sensor signal from a sensor 114configured to sense a physical interaction with a mobile device 309. Thesensor 114 may detect both a direction and magnitude of the user'sinteraction. For example, if a user jerks the mobile device away fromher body, the sensor 114 may detect both the speed with which the devicewas moved as well as the direction. In another example, the sensorsignal may be associated with a user interaction wherein the user dragsa virtual message object toward virtual gateway 212. In this way, thesensor signal may comprise a gesture directed toward the virtualgateway. In another example, the sensor signal may be associated withthe mobile device 102 having been tilted.

Then, processor 110 determines a virtual force based at least in part onthe sensor signal 310. The processor 110 may determine both a directionand a magnitude of the virtual force. For example, the force may be in adirection perpendicular to the virtual objects and at a low intensity.In another example, if the user tilts the mobile device, the processor110 may determine a force representing gravity, pulling virtual objectsin the direction the user tilted the device. In other embodiments, theprocessor 110 may determine a force that varies in direction orintensity over time.

Next, the processor 110 applies the virtual force to a virtual messageobject within a virtual message environment 312. The virtual messageobject will then move within the virtual message environment based, atleast in part, on the magnitude and direction of the virtual force. Thevirtual message object's behavior may further be defined by datacontained in a data store. This data defines characteristics of thevirtual message object's interaction in the virtual message environment.For example, the virtual message object may be in the shape of an egg,and have a characteristic defining a brittle surface. Then, if a virtualforce of a high magnitude is applied to the surface of the virtualmessage object, the object may crack. In another example, the virtualmessage object may have a characteristic which defines a solid ball.When a virtual force of high intensity is applied, the ball may roll inthe direction of the virtual force.

Then, the processor 110 determines whether to transmit the virtualmessage object 314. This determination may be based at least in part onthe virtual force and the status of a recipient. Processor 110 mayanalyze the speed and angle of the force to determine if the virtualmessage object's trajectory will take it through the virtual gateway212. If processor 110 determines that the trajectory will not carry thevirtual message object through the virtual gateway 212, then processor110 may determine not to transmit the virtual message object. But if thetransmission characteristic of a virtual message object will carry itthrough the virtual gateway 212, then processor 110 may transmit thevirtual message object. Additionally, processor 110 may determinewhether to transmit the virtual message object based, at least in part,on the status of a recipient. For example, if the recipient has turnedtheir mobile device off or disconnected it from the network, processor110 may determine not to send the virtual message object. In anotherexample, if the status of a recipient's mobile device is set to“hidden,” processor 110 may determine not to send the virtual messageobject.

If at 314, processor 110 determines that a virtual message object shouldnot be transmitted, then processor 110 may determine a haptic effectassociated with a failed transmission 315. For example, after processor110 determines that a virtual message object should not be sent, it maydetermine a haptic effect simulating the virtual message object bouncingagainst the virtual gateway 212 and staying in the virtual messageenvironment 210.

Then, processor 110 determines a transmission characteristic of thevirtual message object based, at least in part, on the sensor signal316. In one embodiment, the sensor signal is associated with a hurriedor forceful gesture, so processor 110 determines a corresponding hurriedor forceful transmission characteristic. In another embodiment, a sensorsignal may be associated with a gentle or slow gesture; thus, processor110 may determine a corresponding gentle or slow transmissioncharacteristic.

In some embodiments, the sensor signal may be associated with an angleof transmission of a virtual message object. For example, a user maymove a virtual message object toward the virtual gateway at an angle. Inthis case, the virtual message object travels through the virtualgateway at an angle; therefore, processor 110 may determine an angulartransmission characteristic. Alternatively, if a user sends a virtualmessage object straight through the virtual gateway, the processor 110may determine a straight transmission characteristic

Finally, the processor 110 transmits the virtual message object and thetransmission characteristic of the virtual message object 320. In someembodiments, transmission will occur when the virtual message objectpasses through the virtual gateway 212. When a virtual message object issent through the virtual gateway 212, the virtual message object maydisappear from the local virtual message environment 210. Thedisappearance may occur at substantially the same time as the virtualmessage object is transmitted across a network. If the virtual messageobject is not successfully transmitted to the recipient, it will remainin the virtual message environment 210. This provides the user withsimple information regarding the status of the network connection or thestatus of the recipient device.

In one variation, when a virtual message object leaves the virtualmessage environment 210, processor 110 transmits a haptic signal to anactuator 118 alerting the user that the message has been successfullytransmitted. For instance, processor 110 may determine a haptic effectthat simulates an arrow hitting a wall.

FIG. 4 is a flow diagram of a method for transmitting haptic messagesaccording to one embodiment of the present invention. FIG. 4 shows anembodiment wherein a virtual message object is received by a recipientmobile device.

In method 400, the recipient device's processor receives a signalassociated with a virtual message object 402. The signal may be receivedfrom a network interface which is communicatively connected to anexternal network such as a cellular network, intranet, or the Internet.For example, the signal may have been transmitted across a network byanother mobile device connected to that network. The signal associatedwith the virtual message object comprises data defining the virtualmessage object's characteristics. For example the signal may comprisedata defining characteristics such as a virtual message object's size,shape, transmission characteristic, data type, and contents.

Then the recipient device's processor determines a haptic effect based,at least in part, on the transmission characteristic of the virtualmessage object 406. For example, if the sending mobile device is gentlytilted toward a virtual gateway when the virtual message object wassent, then the transmission characteristic may comprise a low speed. Therecipient device's processor will then use that transmissioncharacteristic to determine a haptic effect comprising a gentlevibration. The gentle vibration simulates the virtual message objecthitting a boundary of the recipient virtual message environment at a lowspeed. In contrast, a haptic effect based on a high speed transmissioncharacteristic may comprise a strong jolt, to simulate the virtualmessage object arriving in recipient's virtual message environment at ahigh speed.

Finally, the recipient device's processor transmits a haptic signal toan actuator configured to output the haptic effect 408. The actuatorwill then output a haptic effect based, at least in part, on thissignal.

Illustrative Scenarios for Generating and Transmitting Haptic Messages

FIGS. 5 a and 5 b are illustrations of generating haptic message objectsaccording to one embodiment of the present invention. FIG. 5 a comprisesa mobile device 500. A user may generate the virtual message object byplacing the mobile device 500 in generate mode. The user then moves themobile device in a predefined pattern. This motion is detected by thesensor 114 which transmits a sensor signal associated with the motion ofthe mobile device to the processor 110. Processor 110 will thendetermine a personal token based at least in part on the sensor signal.For example, a user may wish to define a personal token in the form of aheart. In order to define this personal token, a user may perform agesture which moves the mobile device in the shape of a heart 512. Thisgesture may for example move the mobile device upward and over, thendownward at an angle. The gesture may then move the mobile device upwardand then over and down at an angle until the mobile device is insubstantially the same position as it started. The sensor 114 will thentransmit a signal associated with the heart shaped gesture to theprocessor 110. Based on this gesture, the processor 110 will generate avirtual message object comprising a personal token in the form of aheart 514. In other embodiments, the user may enter virtual messageobjects of other shapes.

In some embodiments the user may create a virtual message object with auser defined shape. In such an embodiment, the display 116 may show aspray-paint cant. The user may then press the spray-paint can, and movethe mobile device in a pattern. The sensors 114 may detect this motionand transmit a sensor signal corresponding to the motion to processor110. Based on the received signal the processor 110 will generate avirtual message object substantially corresponding to the shape of thedetected movement. In some embodiments, a user may move the mobiledevice in a pattern substantially approximating letters. In such anembodiment, the processor 110 may generate text which corresponding theletters. The user may then append this text to a virtual message object.

FIG. 6 is an illustration of generating a haptic message according toone embodiment of the present invention. FIG. 6 shows mobile device 600.Mobile device 600 comprises a virtual message environment 612 which isdisplayed on touch screen display 610. The virtual message environmentcomprises a virtual message object 614 in the shape of a heart. Thevirtual message object 614 comprises a personal token which will exhibitthe same characteristics on a recipient's mobile device as it exhibitson the sender's mobile device.

The virtual message object may comprise animation and a haptic effect.For example, a virtual message object in the form of a heart may beanimated to appear to be beating or throbbing. Arrow 618 shows lineswhich represent a haptic effect associated with the virtual messageobject. The virtual message object may further comprise a beating orthrobbing haptic effect to representative of a beating heart.

Arrow 620 shows a finger touching the virtual message object. When theuser interacts with the virtual message object, the touch-screen display610 detects the user interaction and transmits a signal associated withthe user interaction to the processor 110. Based on the received signal,the processor 110 may calculate a transmission characteristic of thevirtual message object. For example a user may flick the virtual messageobject toward the virtual gateway, causing the mobile device to send thevirtual message object. In another embodiment, the mobile device may usethe microphone to detect a user interaction with the virtual messageobject. For example the microphone may detect that the user has blowninto the mobile device. The microphone may then transmit a signal to theprocessor 110 associated with the user blowing into the microphone.Based on this signal, the processor 110 may determine a transmissioncharacteristic of the virtual message object. For example the processor110 may determine a transmission characteristic associated with a senderblowing a kiss to a recipient.

FIG. 7 is an illustration of generating a haptic message according toone embodiment of the present invention. Prior to sending the message,the user may define additional characteristics of the personal token.FIG. 7 shows a mobile device 700 after the user has double clicked thepersonal token 714. When the user double taps the personal token 714, avirtual keyboard 712 appears on touch-screen display 710. The user maythen type a short message and click a button associated with asubmission to append the message to the personal token 714. For example,arrow 716 shows that the user has entered the message “I miss you!” tothe personal token 716. In other embodiments, the virtual keyboard 712may comprise an old fashioned typewriter. In such an embodiment theprocessor 110 may transmit audio and haptic signals corresponding to theclanging keys of the typewriter. Actuator 118 and Speaker 120 mayreceive these signals and output corresponding haptic and audio effects.

FIGS. 8 a and 8 b are illustrations of deleting a haptic messageaccording to one embodiment of the present invention. A user may decidenot to send a personal token and instead to delete it. FIG. 8 a showsmobile device 800, which comprises a touch-screen 810. Touch-screen 810comprises a personal token 812 in the form of a heart. The user hasdecided to delete personal token 812. Thus, the user moves their fingerover touch-screen display 810 in an X-pattern 814. Touch-screen display810 detects this interaction and transmits a signal associated with theX-Pattern to processor 110. Based at least in part on this signal,processor 110 determines that the personal token 812 should be deleted.Thus, processor 110 removes the personal token from display 810.

FIG. 8 b shows mobile device 800 comprising touch-screen display 810 ashort time after the user has deleted the personal token. The processor110 may remove the personal token from display 810 in a variety of ways.For example, in one embodiment, processor 110 may remove the personaltoken by causing it to slowly fade off touch-screen 810. In anotherembodiment, processor 110 may remove the personal token by causing it topop and quickly disappear from touch-screen 810. In some embodiments,processor 110 will calculate a haptic effect associated with the removalof personal token 812. Processor 110 will then transmit a signalassociated with the haptic effect to actuator 118, which then outputsthe haptic effect.

Illustrative Method for Generating and Transmitting Haptic Messages

FIG. 9 is a flow chart illustrating a process of generating andtransmitting a haptic message according to one embodiment of the presentinvention.

The method 900 begins when the processor 110 receives a sensor signal inresponse to a user interaction 902. The user interaction may be a usermoving the mobile device 102 in a predefined pattern. The predefinedpattern may be, for example, moving the mobile device 102 in a heartshaped pattern.

Next, the processor 110 determines that the user indicated a personaltoken, based at least in part on the sensor signal 904. A personal tokenmay be a virtual message object comprising a personal message. Thevirtual message object exhibits the same characteristics in arecipient's mobile device as in the sender's mobile device. In oneembodiment, the personal token has a shape that visually reflects theinteraction associated with the received sensor signal. For example ifthe sensor signal is associated the motion of the device thatsubstantially corresponds to the shape of a heart, the personal tokenmay take the form of a heart.

Then, the processor 110 receives a sensor signal associated with agesture from a touch-sensitive interface 906. In one embodiment thetouch-sensitive interface may be a touch-screen display. In otherembodiments the touch-sensitive interface may be a trackball orpush-button. In some embodiments, the gesture may comprise a double-tapon a button displayed on the touch-screen display.

Next, the processor 110 causes the display 116 to display a userinterface 908. In one embodiment, the user interface may be for examplea virtual keyboard for text entry. In other embodiments, the userinterface may provide an element for adjusting the color or hapticfeedback associated with a personal token.

Then, the processor 110 receives user input entered via the userinterface 910. In one embodiment, the user inputs text on a virtualkeyboard. For example, the user may type a short text message associatedwith the personal token. In other embodiments, the user input mayinclude a color, shape, or specific haptic feedback associated with thepersonal token.

Then, the processor 110 causes the display 116 to change based at leastin part on the user input 912. In one embodiment, processor 110 maychange the display 116 to show a textbox comprising text that the userentered. In other embodiments, processor 110 may change the display 116by altering the shape, color, or other characteristics of the personaltoken. For example, in one embodiment, the user enters a text messageassociated with a personal token in the shape of a heart. When theprocessor 110 associates the text message with the heart, the processor110 causes the heart to begin beating.

Next, the processor 110 generates a haptic signal based on the personaltoken and on the user input 914. In one embodiment, for example, thepersonal token may be in the form of a heart. In this embodiment, thehaptic signal may correspond to a beating or throbbing heart. In otherembodiments, the haptic signal may be associated with anotherinteraction of the personal token. For example the haptic signal may bebased on a particular haptic effect that a user has associated with amessage, such as a vibration or clicking; or the haptic signal may bebased on some other parameter, such as the color of a personal token.

Next, the processor 110 receives a microphone input associated with auser blowing into the microphone 916. For example, in one embodiment auser may blow on a microphone incorporated into the mobile device 102.In another embodiment, a user may blow at a region of the device, or inthe direction of the whole device. In all of these examples, the user'sbreath is detected by the microphone, and the microphone then transmitsa signal to the processor 110 associated with the user's blowing.

In response, the processor 110 sends the message including the personaltoken via the virtual gateway 918. For example, in an embodiment inwhich the personal token is a heart, the user blows on the microphone asif blowing a kiss. In response, processor 110 causing the message to betransmitted to the intended recipient. In another embodiment, theprocessor 110 transmits a personal token after applying a virtual forceto the token. In such an embodiment, the virtual force carried thevirtual message object through a virtual gateway. In such an embodiment,the processor 110 may have determined the virtual force based at leastin part on a sensor signal associated with a user flicking thetouch-screen display.

FIG. 10 is a flow chart illustrating a process of generating andtransmitting a haptic message according to one embodiment of the presentinvention. Process 1000 begins when processor 110 receives a messageincluding a personal token 1002.

Next, the processor 110 receives a user input indicating selection ofthe message 1004. In one embodiment, a touch-screen display may detectthe user input, while in other embodiments a track ball 122 may detectthe user input. In some embodiments the user input may comprise atapping or double-tapping of the message. Or, in other embodiments theuser input may comprise tilting or otherwise manipulating the mobiledevice 102.

Then, processor 110 causes display 116 to display a user interface 1006.In some embodiments, the user interface is a virtual keyboard forentering text. In such an embodiment, the keyboard may appear as aQWERTY keyboard. In other embodiments the keyboard may appear as anold-fashioned typewriter, and the mobile device may output audio andhaptic effects corresponding to the clanging keys of the typewriter whenthe user enters text. In some embodiments, the user interface may be atext pad on which the user can write using a touch-screen display. Forexample, a user may use their finger to write their signature on thetouch-screen display. In such an embodiment, the user may also assign ahaptic effect associated with their signature. For example, a user maycreate a virtual signature which comprises their written signature and ahaptic effect approximating a basketball bouncing on a court. The hapticeffect may also be derived from the signature itself, i.e., theattributes of the writing (strokes, loops, etc.) may be translated tosubstantially similar haptic effect parameters (intensity, duration,periodicity, etc.) In other embodiments, the user interface may be aninterface for modifying other characteristics of the personal token. Forexample the interface may enable a user to modify the shape, color, orhaptic effect associated with the personal token.

Next, the processor 110 receives a user input 1008. In some embodimentsa touch-screen display may receive the user input. For example, the usermay enter text on the touch-screen display. In other embodiments, theuser input may be received by other sensors within the device. Forexample, the user may enter input by tilting or otherwise manipulatingthe mobile device.

Then, processor 110 receives a sensor signal indicating that the userhas tilted the mobile device 1010. In some embodiments a gyroscope, anaccelerometer, a GPS, or other sensor capable of detecting movementtransmits the sensor signal to the processor 110. For example, agyroscope may determine that the user has tilted the mobile device to a45-degree angle, and transmit a signal associated with that amount oftilt to the processor 110.

Then, the processor 110 sends the message via the messaging gateway1012. In some embodiments, the messaging gateway will appear at the topof the display and comprise an indication of the intended recipient. Insuch an embodiment, a message is sent when a virtual representation ofthe message travels through the messaging gateway.

In some embodiments of transmitting haptic messages, a user may wish tosend a pre-written form message to a recipient. FIGS. 11 a and 11 b areillustrations of generating a haptic message according to one embodimentof the present invention. Figure 11 a comprises mobile device 1100. Auser may generate the virtual message object by placing the mobiledevice 1100 in a mode for generating a virtual message object. The userthen moves the mobile device in a predefined pattern. This motion isdetected by the sensor 114 which transmits a sensor signal associatedwith the motion of the mobile device to the processor 110. Processor 110will then determine a virtual message object based at least in part onthe sensor signal.

In some embodiments the processor 110 may determine that the motion isassociated with a predefined virtual message object that comprises abusiness token. A business token is a business-related virtual messageobject that exhibits the same or substantially the same characteristicsin a recipient's virtual message environment as it does in the sender'svirtual message environment. For example, a predefined business tokenmay take the form of a nail, and include the text and/or audio message,“You nailed it!” The business token may further comprise a haptic effectassociated with the hammering of a nail. A recipient of the businesstoken will feel this haptic effect when the business token arrives intheir mobile device. Such an embodiment may provide the sender with theability to provide a tangible response to a message.

In order to send the business token, a user may perform a gesture whichmoves the mobile device in a pre-defined pattern. For example a user maymove the mobile device 102 up and down, simulating swinging a hammer1110. Sensor 114 may detect the gesture and transmit an associatedsignal to processor 110. Processor 110 then determines whether thegesture matches the pre-defined pattern for the virtual nail businesstoken. And based on the gesture, processor 110 will generate a businesstoken 1130 on the display 1120, as shown in FIG. 11 b. In someembodiments, processor 110 may determine a haptic effect associated withthe virtual nail. Processor 110 will then output the haptic signal toactuator 118, which outputs the haptic effect. In some embodimentsprocessor 110 waits for an indicative user interaction to send thebusiness token. In other embodiments, the processor 110 generates thebusiness token and then automatically sends it.

FIGS. 12 a and 12 b are illustrations of transmitting a haptic messageaccording to one embodiment of the present invention. FIGS. 12 a and 12b comprise mobile device 1200, which has just received a business tokenin the form of a virtual nail. Device 1200 comprises a display 1210which comprises the recently received business token 1220. In someembodiments, upon receipt of the business token, mobile device 1200 mayoutput a haptic effect associated with the business token. In one suchembodiment, the haptic effect may approximate the pounding of a nail. Inother embodiments, the mobile device may output another haptic effect.In yet another embodiment, the mobile device may not output a hapticeffect

In FIG. 12 b, the mobile device 1200 comprises a touch-screen display1210. The touch-screen display comprises a business token 1220. When theuser interacts with the business token 1220, the touch-screen transmitsa signal associated with the user interaction to processor 110. Based atleast in part on this signal, processor 110 displays a messageassociated with the business token to the user. In the embodiment shownin FIG. 12 b, the text associated with the virtual nail business tokenis “You nailed it!” 1230. In other embodiments, the user may definedifferent text to associate with the business token.

FIG. 13 is a flow chart for a process for generating and transmitting ahaptic message according to one embodiment of the present invention.FIG. 13 shows process 1300, which begins when processor 110 receives atleast one sensor signal from at least one sensor 114 of a mobile device,the at least one sensor signal associated with a movement of the mobiledevice 1302. In some embodiments, the sensor 114 may comprise anaccelerometer, a GPS, or other sensor capable of detecting movement. Themovement may comprise any gesture which the sensor 114 is capable ofdetecting. For example, in some embodiments, the movement comprises amovement approximating the shape of a heart. In other embodiments, themovement comprises a movement approximating a hammering gesture. Instill other embodiments the movement may approximate tossing a rope.

Then, processor 110 determines a token to be displayed in a userinterface based at least in part on the at least one sensor signal 1304.The token takes a shape related to the movement of the mobile device. Insome embodiments the token may take the shape of a nail or a heart. Inother embodiments, the token is in another shape, such as a balloon,bubble, rope or dart.

Next, the processor 110 causes the token to be displayed 1306. The tokenis displayed in a display 116 of the mobile device. In some embodiments,display 116 may further comprise a graphical user interface. In such anembodiment, display 116 may show the token in the graphical userinterface. In further embodiments one or more additional tokens may alsoappear along with the token in the graphical user interface.

Then, a sensor 114 detects a user interaction with the token 1308. Insome embodiments, the sensor 114 may be a touch-screen display. In otherembodiments the sensor 114 may be a track-ball 122. In still otherembodiments, the sensor 114 may be a motion sensor such as anaccelerometer, gyroscope, or GPS. In some embodiments, the userinteraction comprises a single tap or a double-tap on the surface of thetoken. In other embodiments, the user interaction may comprise tiltingor shaking the mobile device 102. In such an embodiment, the processor110 may apply a virtual force to the virtual message object in responseto the detected interaction. In still other embodiments, the sensor 114may comprise a microphone. In such an embodiment, the user interactionmay comprise blowing on the microphone. In such an embodiment, theprocessor 110 may apply a force to the token simulating the effects ofthe user blowing on the token. For example, in one embodiment, a tokenmay be in the form of a bubble. When the user blows on the microphone,the processor 110 may determine a force acting on the bubble whichsimulates the user blowing a bubble to the recipient.

Finally, the processor 110 transmits a signal associated with the tokento a recipient 1310. In some embodiments, the processor 110 may transmitthe signal via network interface 112. In some embodiments, the mobiledevice may comprise a graphical user interface comprising a messaginggateway. In some embodiment, the messaging gateway may compriseinformation identifying the recipient. In some embodiments, after theprocessor 110 transmits a signal associated the token, the processor 110removes the token from the display 116.

Transmitting Haptic Messages Using a Real-Time Link

When using a mobile device 102, a user may wish to interact with anotheruser in real-time. One embodiment of the present invention provides thecapability for users to transmit haptic messages over a real-time link.For example, in one embodiment, a first user can interact with atouch-screen of the mobile device 102. The interaction causes an objecton the touch-screen to be modified. For example, the touch-screen may beblank, and as the user interacts with the screen, the processor 110generates a line tracking the user's movements across the touch-screen.In such an embodiment, the line may substantially follow the point ofcontact between the user and the touch screen.

In such an embodiment, the changes to the first user's touch-screen aresubstantially simultaneously duplicated on the touch-screen of a seconduser's mobile device. The second user can similarly drag a finger overthe touch-screen of the second user's device. The second user'sinteractions are subsequently tracked by a second line that is presenton both the first user's touch-screen and the second user's touchscreen.

In such an embodiment, when the two lines touch or overlap, a touch orcollision is detected by the processors on the first and second mobiledevices. And in response, both devices output a haptic effect indicatingthe interaction. In such an embodiment, the two users can touch oneanother in real time via haptic messaging.

In another embodiment, a user may modify a message or other objectdisplayed on the screen of the sending device, and at substantially thesame time, the message or object is modified on the recipient's device.The changes to the messages or objects may go beyond text updates andcomprise changes to virtual properties of the objects, haptic effectsassociated with the objects, or other changes. In this way a user canuse a mobile device to send real-time haptic messages.

For example, in some embodiments, two linked mobile devices eachcomprise a touch-screen display. In such an embodiment, the users ofeach device draw images on their respective mobile devices and theiroutput is displayed on the recipient's device in substantiallyreal-time. In one embodiment, if the sender's and recipient's fingerscrossed the same relative location on their respective touch-screendisplays, the mobile devices would each output audio and haptic effectsassociated with a collision or touching.

In another embodiment, the users may interact with an image that issimultaneously displayed on both users mobile devices. In such anembodiment, the users could simultaneously modify the image. Themodifications would appear on both mobile devices substantiallysimultaneously. For example, one user could use their touch-screen todraw features on an image displayed on both mobile devices. In such anembodiment, for example, a user could crop the image, while the otheruser watches the cropping occur. In a further embodiment, a user coulddraw a comical mustache on an image, while the other user watches. Thisembodiment could be used for editing, or simply to entertain both users.Such an embodiment may be further used while both users are connectedvia a telephone call or other audio link.

In another embodiment, the mobile device generates a direct haptic linkto another mobile device to play a game. For example, the users couldplay a game of virtual tennis. In such a game, a user could flick atennis ball to a recipient via their touch screen. The recipient couldthen flick the tennis ball back to the sender. In such an embodiment,the tennis ball may further comprise a haptic effect that represents theforce with which the user hit the ball. In such an embodiment the userscould also carry on a conversation via a telephone or other audio linkavailable through the mobile devices. The game could be used to fillawkward pauses in conversation and provide a sense of shared spacebetween the users.

In another embodiment, while in a call or chat, one user may transmitvirtual message to a recipient. The recipient may modify these objectsand transmit them back. Such an embodiment may add ambient affects tothe conversation, and serve to fill silence, or set the mood of theconversation. These objects may further serve to allow the users to worktogether to create a virtual message object that comprises a separatedocument. For example, two users may send a virtual message objectcomprising a text document. Each user may edit the document, and sendthe draft to the other user for review.

In one embodiment, a user may wish transmit a haptic gesture associatedwith a champagne toast to a recipient. The user may make a pouringgesture with their mobile device. A sensor 114 of the mobile device maydetect the pouring gesture. The sensor 114 transmits a signal to theprocessor 110 associated with the tilting of the mobile device,Processor 110 may then determine that the user is attempting to send achampagne toast. Thus, the processor 110 transmits a signal to thedisplay which causes the display to output an image of a champagnebottle. The processor 110 may further output an audio signal associatedwith the pouring of champagne to the speakers. Additionally, theprocessor 110 may output a haptic signal to an actuator associated withthe pouring of champagne. The actuator may then output a haptic signalassociated with the pouring of champagne.

FIG. 14 shows two mobile devices, 1400 and 1450. Mobile device 1400 isthe sending mobile device, and mobile device 1450 is the receivingmobile device. Each of mobile devices 1400 and 1450 comprise a display1410 which comprises a virtual message object in the form of a glass ofchampagne 1420. When a user titles either mobile device, a motion sensor114 such as an accelerometer, gyroscope, or GPS determines that the userhas tilted the mobile device and transmits a signal to processor 110associated with the tilting. Processor 110 then calculates a virtualforce representing gravity which is applied to the virtual champagne1420. The force of gravity causes the champagne to shift within theglass as shown in both devices 1400 and 1450. In some embodiments, whenthe mobile device shifts, processor 110 determines a haptic effectassociated with the shifting champagne. The processor 110 then transmitsa signal associated with the determined haptic effect to actuator 118which outputs the haptic effect.

Using signals from the sensor 114, the processor 110 determines thelocation of each of mobile devices 1400 and 1450 in relation to eachother. Processor 110 uses the signal to determine if both users haveraised their glasses at substantially the same time. If both devices1400 and 1450 are raised at the same time, processor 110 will determinethat a toast is occurring and determine audio and haptic affectsassociated with the clinking the results when two glasses collide. Theprocessor 110 then transmit signals associated with audio and hapticeffects to actuator 118 and speaker 120. Actuator 118 and speaker 120may then output the determined haptic effect. In some embodiments, thiseffect may be gentle clink as though two crystal glasses have touchedeach other. In other embodiments, the haptic effect may be a thudassociated with two heavy beer steins slamming into each other.

FIG. 15 is a flow chart illustrating a process of transmitting a hapticmessage according to one embodiment of the present invention. Process1500 begins when a sensor 114 detects a user input indicating a pouringgesture 1502. In some embodiments, the sensor 114 may comprise anaccelerometer, gyroscope, GPS or other sensor capable of sensing motion.In some embodiments a user gesture indicating a pouring gesture maycomprise tilting the mobile device to a predetermined angle.

Then, the processor 110 transmits a signal to the display which causesthe display 116 to display a champagne bottle 1504. In some embodiments,rather than a bottle of champagne, a bottle of beer or another beveragemay appear. In other embodiments, a glass comprising a beverage mayappear in place of the bottle.

Next, an actuator and a speaker output effects associated with theopening of a bottle 1506. In some embodiments, the audio and hapticeffects may be effects associated with a cork popping. In otherembodiments, the effects may be associated with the pouring of abeverage.

Then, a sensor 114 receives a user input that the pouring is completed1508. In some embodiments, the sensor 114 may be an accelerometer,gyroscope, GPS or other sensor capable of sensing motion. In otherembodiments, the sensor 114 may be a touch-screen or a track-ball 122.In some embodiments, the user input may comprise tilting the mobiledevice. In other embodiments the user input may comprise a gesture onthe touch-screen display or a gesture made with the track-ball 122.

Next, the processor 110 transmits a signal to the display which causesthe display to show a champagne glass 1510. In some embodiments thesignal may cause the display to show a beer stein or other glass. Inother embodiments, the signal may cause the display to show a bottleassociated with some other type of beverage.

Then, a sensor 114 receives an input indicating the touching of glasses1512. In some embodiments, the sensor 114 may be an accelerometer,gyroscope, GPS or other sensor capable of sensing motion. In otherembodiments, the sensor 114 may be a touch-screen or a track-ball 122.In some embodiments the input may comprise raising the mobile device asthough it is a glass of champagne in a toast. In other embodiments theinput may be a gesture made on the touch-screen display.

Next, the processor 110 transmits a signal to the display, actuator andspeakers associated with a toast 1514. In some embodiments the signalmay comprise a visual signal associated with glasses touching, and audioand haptic signals associated with the light clink of two crystalglasses. In other embodiments the effects may be associated withdifferent types of glassware. For example, the signal may comprise avisual signal associated with two heavy beer steins, and audio andhaptic signals associated with heavy glasses impacting each other.

In one embodiment, a user may establish a direct virtual connectionbetween two mobile devices by connecting both devices with a virtualrope. Devices mimicking the behavior of a real rope may cause vibrationsthat are reminiscent of those emitted by ropes when they are slackenedand taught with tugging gestures.

FIGS. 16 a, 16 b, and 16 c are illustrations of transmitting hapticmessages according to one embodiment of the present invention. In FIG.16 a, a mobile device 1600 is in communication with mobile device 1602.Each mobile device comprises a display 1604. Initially, mobile device1602 comprises one end of a tug rope 1606, the rope attached to a pullor tug at one end, and unattached at the other end. Mobile device 1600initially comprises an empty anchor. In order to initiate a connection,a user of mobile device 1600 may toss one end of the rope toward anotheruser. For example, in one embodiment, the user may open a virtualgateway to the recipient mobile device, and flick the end of the rope inthe direction of the virtual gateway. In another embodiment, the usermay throw the rope by jerking the entire mobile device in the directionof the virtual gateway. The virtual tug rope may span the entire virtualspace between the two devices, and ultimately arrive at mobile device1600. In some scenarios, the virtual rope may not be able to span thelength of the virtual space between the devices. For example, the mobiledevice 1600 may be too far way (such as in a different area code, state,or country) for the virtual rope to arrive. Alternatively, a user of thea mobile device may update a status such that certain virtual objectsare automatically blocked.

When the rope appears on the display of mobile device 1600, the mobiledevice may generate a haptic and/or sound effect mimicking a ropelanding in the virtual environment of the mobile device. Through suchnon-visual cues, mobile device 1600 may alert the user that a virtualtug rope has been tossed in their direction, without the user beingrequired to look at the mobile device.

The user of the mobile device 1600 may catch the virtual tug rope. Insome embodiments, the user may catch the tug rope by moving the mobiledevice in a catching gesture, such as a quick twirl of the communicationdevice, or by pressing a specific button. In some embodiments, if theuser of mobile device 1600 is not paying attention, they will not catchthe rope and establish the connection. When the rope is not caught by areceiving device, the sending user may tug the virtual rope to have itcome flying back into their mobile device, indicating that theconnection has not been established. However, if the receiving user doessee, feel and/or hear the rope arrive, they may catch the rope andsecure it to their device.

In FIG. 16 b, the user of mobile device 1600 has caught the virtual tugrope 1606 sent be mobile device 1602. And the user has secured virtualtug rope 1606 to a virtual anchor 1608. The users of mobile devices 1600and 1602 now share the same virtual physical object which spans acrosstheir shared virtual physical space.

In FIG. 16 c, the user of mobile device 1602 may yank or tug on thevirtual tug rope, which may cause mobile device 1600 to generate ahaptic effect mimicking the results of a taught rope 1610 pulling onanchor 1612. In response the user of mobile device 1600 may tug on therope, which may cause mobile device to generate a haptic effectcorresponding to the taught rope 1610 pulling on anchor 1614.

In other embodiment of the present invention, a user may form areal-time link to transmit information in a format other than a message.FIG. 17 is an illustration of transmitting haptic messages according toone embodiment of the present invention. As shown in FIG. 17, a mobiledevice 1700 comprises a display 1702. Display 1702 comprises a hapticcontact list 1704. Each contact comprises a name and a haptic statusshown in a haptic window. In one embodiment, when a user of mobiledevice 1700 touches the haptic status window of a contact, the user mayfeel a haptic effect corresponding to the status of the person listed inthe haptic contact list. In a further embodiment, the mobile device maytransmit a signal to the mobile device of the person listed in thehaptic contact list. The signal may comprise a haptic signal to alertthe person in the haptic contact list that someone is interested intheir status. For example, while a first user swipes their finger acrossa second user's contact entry, the first user feels the second user'sstatus. At the same time, the swipe gesture by the first user istransmitted to the second user's device, which may generate a hapticeffect perceptually equivalent or similar to the duration and intensityof the finger swipe. In another embodiment, the first user may taprepeatedly on the second user's contact list entry, mimicking knockingon a door or window, which transmits a haptic, audio, and visualknocking effect to the second user, serving as an invitation to initiatea communication session.

In another embodiment, as the user moves mobile device 1700, the mobiledevice's processor 110 may determine a motion profile based at least inpart on sensor signals received from a sensor 114. In some embodimentsthe sensor 114 may comprise a GPS sensor, accelerometer, or other sensorcapable of detecting movement or location. Then, the processor 110 maytransmit the user's motion profile to other mobile devices which listthe user in their haptic contact list. The contact list on eachcommunications device may be updated with the user's motion profile inreal-time, so that a user may be able to determine the current activityof a person on their contact list by looking at their haptic statuswindow.

In FIG. 1700, the haptic status of the first contact, David, is shown asa jumbled display of dots with no particular pattern 1706. This mayindicate that David's communication device is in motion, possiblyindicating that David is walking The haptic status of the secondcontact, Remy, is represented as a stable, horizontal line 1708. Thismay indicate that Remy is sitting still, or alternatively, that themobile device has been laid flat on a table. The haptic status of thethird contact, Chris, is represented as a relatively flat vertical line1710. This may indicate that Chris is holding the mobile device in anupright position. In some embodiments, the haptic status of each contactmay be deliberately vague, so as to provide some privacy to each userwhile providing other users some information regarding their status.

Although FIG. 17 depicts the contact list with several entries on asingle page, other variations are possible. For instance, each contactmay have their own dedicated page, screen, or virtual object. Zooming inon an individual contact may provide the user with a more accurate viewof that contact's status. Although haptic contact list 1704 depicts eachcontact's status as a box full of balls, other methods for displayingstatus may be utilized. For instance, the haptic inbox may use iconssuch as a heart representing fast movement, a sleeping icon representingno movement, or other graphics to provide status information for eachcontact.

FIG. 18 is a flow chart illustrating a process of transmitting hapticmessages according to one embodiment of the present invention. Process1800 begins when processor 110 receives a first sensor signal from afirst sensor 114, the first sensor signal associated with a movement ofthe mobile device 1802. In some embodiments, the sensor 114 may be anaccelerometer, gyroscope, GPS or other sensor capable of sensing motion.In some embodiments, the user gesture may comprise moving the mobiledevice in a predefined pattern. For example, in one embodiment the usergesture may comprise tilting the mobile device like a champagne bottle.In another example, the user gesture may comprise a movementsubstantially approximating the shape of a heart. In another embodiment,the user gesture may comprise pounding the mobile device like a hammer.In still another embodiment, the user gesture may comprise tossing orflipping a rope.

Next, processor 110 receives a second sensor signal from atouch-sensitive interface of the first mobile device, the second sensorsignal associated with a user interaction 1804. In some embodiments,display 116 may comprise a touch-sensitive interface such as atouch-screen display. In other embodiments, the touch-sensitiveinterface may comprise track-ball 122. In some embodiments, the userinteraction may comprise a user interaction with a graphical userinterface shown on display 116. In such an embodiment, the userinteraction may comprise double-tapping a portion of the graphical userinterface. In another embodiment, the user interaction may compriseentering text which is appended to a virtual message object. In otherembodiments, the user interaction may comprise finger painting on thesurface of the touch-screen display.

Then, processor 110 determines a change in a display 116 of the firstmobile device, based at least in part on the second sensor signal 1806.In some embodiments, the change may comprise displaying a trail whichfollows the user's finger as it moves across the surface of thetouch-screen display. In other embodiments, the change in the displaymay comprise modifying a virtual object on the display. For example, thedisplay may comprise an image, and the user interaction may comprisemodifications to the image. In other embodiments, the change in thedisplay may comprise displaying a new virtual object, such as bubbles, aheart, a nail, a rope, or a champagne bottle.

Next, the processor 110 transmits a first data signal to a second mobiledevice, the first data signal comprising data associated with the userinteraction and the movement of the first mobile device 1808. In someembodiments, processor 110 may transmit the data signal via networkinterface 112. In some embodiments, the processor 110 transmits thefirst data signal substantially simultaneously to receiving user inputvia the touch-sensitive interface. In other embodiments, the processor110 does not transmit the data signal until receiving a user interactionindicating the processor 110 should transmit.

Then, the processor 110 receives a second data signal from the secondmobile device 1810. In some embodiments, the processor 110 may receivethe data signal from network interface 112. In some embodiments, theprocessor 110 transmits data signals to the second mobile device, andsubstantially simultaneously receives a signal from the second mobiledevice. In some embodiments, the second data signal comprises datacorresponding to a user interaction with a touch-sensitive interfacewith the second mobile device.

Next, processor 110 determines a second change in the display of thefirst mobile device based at least in part on the second data signal1812. In some embodiments, the received data may correspond to a changeon the display of the second mobile device. In such an embodiment, thechange to the display of the first mobile device determined by processor110 may correspond to the change in the display of the second mobiledevice. For example, the user of the second mobile device may move theirfinger across the second mobile device to draw a picture. The secondmobile device may then transmit a corresponding second signal to thefirst mobile device. The processor 110 of the first mobile device maythen modify its display in a way that substantially correspond to thedisplay of the second mobile device. In another embodiment, the user ofthe second mobile device may modify a picture on their touch-screendisplay. In such an embodiment, the second user's modifications willappear substantially simultaneously on the display of the first mobiledevice.

Then, processor 110 determines a haptic effect based at least in part onthe second data signal 1814. For example, in one embodiment the seconddata signal may comprise information to corresponding to the user of thesecond mobile device tapping the surface of the second mobile device. Insuch an embodiment, the processor 110 may determine a haptic effectcorresponding to the tapping. In another example, a user interactionwith the first mobile device may cross substantially the same positionas the second user's interaction with the second mobile device. In suchan embodiment, the determined haptic effect may substantially correspondto an impact between the user of the first and the second mobile device.In another embodiment the second data signal may correspond to opening avirtual bottle on the second mobile device. In such an embodiment thedetermined haptic effect may correspond to a cork popping on the bottle.

Finally, the processor 110 transmits a haptic signal associated with thehaptic effect to an actuator 118 configured to output the haptic effect.In some embodiments Actuator 118 may be, for example, a piezoelectricactuator, an electric motor, an electro-magnetic actuator, a voice coil,a linear resonant actuator, a shape memory alloy, an electro-activepolymer, a solenoid, an eccentric rotating mass motor (ERM) or a linearresonant actuator (LRA).
